Abstract: One aspect of the invention provides a system for radiation treatment of a tumor allowing for imaging of the tumor and a surrounding region during radiation therapy and to methods of using such a system. In one embodiment, the system includes a number of radiation detectors positioned in an array to detect radiation scattered from the tumor and the surrounding region. A 3-dimensional image of the tumor is reconstructed from the 2-dimensional scattered radiation projections.

Abstract: Multi-component intermetallic negative electrodes prepared by electrochemical deposition for non-aqueous lithium cells and batteries are disclosed. More specifically, the invention relates to composite intermetallic electrodes comprising two or more compounds containing metallic or metaloid_elements, at least one element of which can react with lithium to form binary, ternary, quaternary or higher order compounds, these compounds being in combination with one or more other metals that are essentially inactive toward lithium and act predominantly, but not necessarily exclusively, to the electronic conductivity of, and as current collection agent for, the electrode. The invention relates more specifically to negative electrode materials that provide an operating potential between 0.05 and 2.0 V vs. metallic lithium.
